Low voltage ride through data acquisition method for photovoltaic power station

The invention provides a low voltage ride through data acquisition method for a photovoltaic power station, and belongs to the technical field of photovoltaic power generation. The method comprises: based on the field test data of a power generation unit, establishing a detailed model for the photovoltaic power station so as to acquire the low voltage ride through data of the photovoltaic power station; and then establishing a low voltage ride through database for the photovoltaic power station. As the method integrates the advantages of a field test with the advantages of model simulation, the realistic problem for directly performing a low voltage ride through test for the photovoltaic power station is difficult is solved and the accuracy and the credibility of the simulation result are improved.
